hasta.

To all whom. t may concern) p Be it known that L Runnin P'. Jianvls, a citizen of the Uni States, residing at Smith Center, in coy ed Smith and State of Kansas, have invented a new' and useful illuminated Si, ed which the folfcated by the numeral 10 and has translulowing is a specification.

It 1S the 'vii the provide a novcigrei iliated sign 'and the invention airneariiy to provide a sign which wili attract and hold attention.

The invention reiates more specifically speaking to signs ont that class in which the sign characters are illuminated by li ht rays of various colors and whereas snc signs have heretofore so constructed that each character orv set of characters would have a distinct color, it is the object of the f ythese reflectors and behind the sign panel.V

present invention to provide means for illuminating the sign characters in such manner that they will be constantl changing not 'only from one' color to anot er but through all of the tints between such changes in color.

Broadly speaking, the invention resides in providing a sign having a character panel and in arranging behind this panel means for emitting vari-colored rays of iight and.

anism being omitted. Fig. 3V is a perspective view of one form of cylinder employed in the sign. Fig. 4 is a view similar to Fig. 3 but showing another form of illuminating cylinder employed. Fig. 5 is also a view similarto Fig. 3 showing still another form cylinders arranged behind the panel an for A of cylinder, and Fig. 6 is a vertical sectional View taken from front to rear of the sign showing the mechanical construction thereof. .l

As heretofore stated, the invention resides in mounting behind a translucent sign panel, means for emitting vari-colored rays of light and for blending such rays and in carrying out the invention there ls'provided a translucent sign panel, a plurallty of lass Speccatioa of Letters Patent. .engineman area tease, isos. serial no. scossa pres invention vto any desired manner, these' characters being 1preferably of ground glamv although glass 5 of other forms or as a matter of fact other y naiterials may be employed if found desir- SAS, A CORPORATION.

rotation, and colored with one or more primary colors, rllnmmating devices 1n said cylinders, and reectors arranged adjacent to the cylinders for blending the vari-colcred rays of light emitted therefrom.

In the drawings, the sign panel is'indicent sign characters 11 arranged therein in This sign panel 10 preferably constitutes the forward wall of a sign box in each end of which is mounted a reflector 12.

4v,These reflectors 12 are disposed at such an angle as to reflectV rays of light upon the :slgn panel and the vari-colored cylinders heretofore mentioned are mounted between In mounting the cylinders above referred has its upper end inturned to extend above the base as at 15 and in the upper face of the base 13 there is formed a step bearing 16 in which a stud 17 is formed axially of a pulley 18 carried upon a disk-like head A19. This head is pro'vided with a peripheral iange l20 and supports the lower end ofone of. the vari-colored cylinders. At the upper end of each cylinder there is provided another head which is indicated by the numeral 21 and this latter head is formed axially with an opening receiving a boss 22 upon the under side of the over-hanging Patented une 1'?, 1913'. v t

portion 15 of the upright 14. This boss 22 is peripherally grooved as is clearly shown in Fig. 6 of the drawings and this groove affords a ball'race as does also a groove 23 which is formed in the edge of theopening in the said head 21, there being bearing balls 24' disposed in these races. The boss 22 is formed with an` axial bore or opening by the cylinders will b'e rotated, although it will be understood that the chain or Sprocket gear' g may be employed instead of the pulley and belt if desire the number of colors in the present instance cated by the numeral 26, are of glass and are each colored one or more primary colors,

being three. In the form of cylinders shown in Fig. 3 of the drawings, the cylinder has clearly deined fields or areas one of red, indicated by the numeral 27, another of blue, indicated by the numeral 28 and a third of green indicated by the numeral 29. In the form of cylinder shown in Fig. 4 the lsame. fields are' provided except that the colors thereof gradually merge so that there is no readily apparent line of demarcation between the fields and inthe form of the f cylinder shown in Fig. 5 the line of demarcation is staggered so that the fields may be said to mingle. In any event, regardless of which form of cylinder is employed, the illuminating lamp 26 wlthin the cylinders will cause the cylinders to emit rays of blue, red and green, for example which rays will be directed not only upon the sign characters 11 but also upon the reliectors 12 from which point they will'be refieeted onto the sign characters. As the light rays intersect or blend, rays of other colors will result and consequently inasmuch as the cylinders are constantly rotating, the sign characters will be constantly changing in color and in tint and the entire sign panel will present the appearance of a spectrum.

-From the foregoing and a reference to Fig. 1, discloses the' fact that everyportion of the translucent sign panel will be illuml- Y nated directly from both of the rotating cylinders and furthermore that the end portions of the sign panel will also be illuminated indirectly from the cylinders by means of the reflectors 12. ySince said roscreento the other and the efectproduced will be a screen illuminated by a constantly shifting repeating spectrum all the colors of which naturally blend one into the other to produce a beautiful and novel eect.

What is claimed ist- In an electric sign, a sign panel, two relectors disposed -one at each end thereof,

said reiectors inclined toward the sign panel; rotatable cylinders disposed adjacent said reiiectors, light sources in said cyllnders each cylinder having longitudinal bands of the primary colors and' adapted to illuminate the sign panel for its entire length, said reflectors assisting the intermixing of the three primary colors," means for rotating said cylinders to produce a constantly shifting continuous spectrum upon said sign panel.

Intestimony that I claim the foregoing as my own, I have hereto affixed my` signature 1n the presence of witnesses.
